ABSTRACT
Background: Bacterial vaginosis (BV) is associated with a high risk of complications, particularly during pregnancy. Objectives: The aims of this study were to determine the prevalence of BV in pregnant women in Dakar, Senegal, and to identify its associated risk factors. Patients and Methods: This prospective cross-sectional study was conducted from July 2020 to March 2021 in pregnant women with 34 to 38 weeks of gestation and seen for their routine prenatal consultation at the Nabil Choucair health center in Dakar, Senegal. Vaginal swabs were taken and examined using the Nugent scoring system for the diagnosis of the BV. Data analysis on SPSS (version 25) was done using the chi-square test to measure the strength of association. A value of p ? 0.05 was considered statistically significant. Results: BV was found in 28.0% (112/400) of the screened women with a median age 24 (21-29) years. A pH >4.5 predictive of BV was found in 80.4% (90/112) of samples. BV was associated with vaginal candidiasis in 49.1% (55/112) while Trichomonas vaginitis was found in 1.8% (02/112). In 80.4% (90/112) of affected women, BV was caused by Gardnerella vaginalis. Mobiluncus spp. was found in 19.6% (22/112) pregnant women in association with G. vaginalis. Symptoms characterized by episodes of pruritus, pelvic pain, burning and/or dyspareunia were seen among 59.8% (67/112) of these women with BV while 40.1% (45/112) of them reported no symptoms. Conclusion: In view of these results and in order to reduce gestational complications and adverse outcomes in the newborn, screening for BV in pregnant women should be favored in developing countries.
ABSTRACT
Background: Data regarding the evolution of antimicrobial resistance are needed to suggest appropriate empirical treatment of urinary tract infections (UTI) in developing countries. To assess the antimicrobial susceptibility of Escherichia coli; the predominant pathogen in community-acquired UTI; a prospective multicenter study was carried out in Dakar; Senegal. Methodology: From February 2004 to October 2006; 1010 non-duplicate E. coli strains were collected from four centres. Antimicrobial susceptibility testing was performed using disk diffusion method according to the recommendations of the CA-SFM (2004). Results: Most of the isolates were resistant to amoxicillin (73.1); amoxicillin- clavulanic acid (67.5); cephalothin (55.8); and trimethoprim/sulfamethoxazole (68.1). Extended spectrum beta-lactamase was detected in 38 strains. The overall resistance rates to nalidixic acid; norfloxacin and ciprofloxacin were 23.9; 16.4and 15.5; respectively. Most of the strains were susceptible to gentamicin; nitrofurantoin and fosfomycin (respective susceptibility rates; 93.8; 89.9; and 99.3). During this period; a significant decrease in sensitivity was observed for cephalothin; fluoroquinolones and trimethoprim/sulfamethoxazole (p0.001). Conclusions: These data suggest that trimethoprim/sulfamethoxazole may no longer be used as empirical treatment for community- acquired UTI in Dakar. In order to preserve the activity of fluoroquinolones for future years; alternatives such as fosfomycin or nitrofurantoin should be considered
